## Abstract
Economic Dispatch (ED) of thermal power plant has a role in maintaining economic power system. The main purpose of ED is to set the control variables of power system so that the generators can generate maximum power according to load demand based on each generator characteristic with lower production cost. In this paper, the economic dispatch will be done in thermal power system using Novel Bat Algorithm (NBA) constrained by voltage stability. NBA is a recent optimization method that is developed build upon bat behavior. The result showed that the NBA can optimize the thermal power system by showing lower price of production cost. The NBA can reduce 9.23% of the production cost. Not only is the production cost smaller but also the power loss obtained by NBA. Voltage stability is also maintained in this research by showing better improvement of critical point with average 0.920 per unit. The proposed method is applied in real system of SULSELBAR 150 kV power system.
